If you don't know them, here are some sites that have information about them:
Japanese: www.mr-hobby.com
English (fan run site, but all the information is really accurate): www.pinky-street.com
And some sites that sell them:
www.freebento.com
www.hlj.com
ekizo.mandarake.co.jp (doesn't turn into a link, but it's real.)
www.plajapan.com
Here's a pic of one of mine that I took a week or so ago:

Her name is Bitter Saki who came with one of the two pinky DVDs, the Keicharou Lucky Version.
So, what do you think of pinkies? If you have any questions, feel free to ask and I'll answer them as best I can.
